BACKGROUND OF THE INVENTION

Creating 3-dimensional geometric structures or puzzles using different building blocks, such as cubes, polycubes (GB420349A; U.S. Pat. No. 3,638,949; GB2143139A; U.S. Pat. Nos. 4,153,254; 4,662,638; 4,844,466; 6,910,691B2; 8,632,072,B2; 5,823,533; 5,393,063; 3,065,970) is well known. The purpose of this invention is to provide an improved set of multi-faced building blocks with the following characteristics: 1) faces that allow mounting different tiles with variety of designs, which provide hints guiding construction of solutions; and 2) edges designed to increase friction of the blocks during the construction process. The multi-faced building blocks can be used to create 3 by 3 by 3 cube puzzle (GB420349A; U.S. Pat. No. 3,638,949; GB2143139A), or any N by N by N cube design (U.S. Pat. No. 4,153,254; 4,662,638; 4,844,466; 6,910,691,B2; 8,632,072B2; 5,823,533; 5,393,063), and can also be used to create 3-D geometric shapes other than cubes (U.S. Pat. Nos. 3,065,970; 8,632,072B2). Unlike traditional 3D-puzzles that are composed of series of pieces that when put together create a single solution (U.S. Pat. Nos. 3,638,949; 4,662,638) or limited number of solutions (U.S. Pat. No. 4,153,254; GB420349A; U.S. Pat. Nos. 4,844,466; 6,910,691B2; 3,065,970), our invention was developed to offer a multiple-solutions design for the puzzle and to provide unlimited options to code the surface of the puzzle pieces in order to generate new solutions. Our invention offers a new way to play with a puzzle, meaning that once all solutions have been solved, we allow the players to change the design with a new set of removable tiles or to program the surface of the puzzle pieces to build a new set of solutions. In addition, commercially known puzzles, such as Think Fun Block by Block Puzzle, have several hundred possible solutions that are very difficult to track and it is difficult for the player to know if he/she has solved a specific solution. Our invention allows the player to recognize and track each new solution using the design elements depicted on the mountable tiles. Finally, to make our multi-faced building blocks more stable and ease the overall construction process we added friction edges to each block. The multi-faced building blocks allow developing children's spatial reasoning skills and can be used for education as well as for entertainment.

BRIEF SUMMARY OF THE INVENTION

Creating 3-dimensional geometric puzzles using different regular or irregular building blocks to construct 3 by 3 by 3 cubes (GB420349A; U.S. Pat. No. 3,638,949; GB2143139A), 4 by 4 by 4 cubes (U.S. Pat. Nos. 4,153,254; 4,662,638; 4,844,466; 6,910,691B2; 8,632,072B2; 5,823,533), or other geometric structures (U.S. Pat. No. 3,065,970; 8,632,072B2) is well known but presents the following challenges: 1) these puzzles lack stability of the structure during the construction; 2) there is a very limited number of puzzle solutions for a set of blocks; 3) for the puzzles, such as Soma cubes, that have several hundred possible solutions it is very difficult to track if the player has solved a specific solution; 4) solving these puzzles is challenging, especially for younger players who may lose interest; and 5) players are not able to create and code new solutions. Our invention provides an improved set of multi-faced building blocks with the following characteristics: 1) softer edges designed to increase friction of the blocks during the construction process; 2) faces that allow mounting different tiles with variety of designs, which provide hints guiding construction of solutions and allow players to complete puzzles; and 3) mountable tiles that code each face of the building block in order to increase the number of solutions within one set of blocks, which makes the puzzle more versatile. Our invention lets players create and code their own new unique solutions using the mountable tiles. Our invention also allows the player to recognize and track each new solution using the design elements depicted on the mountable tiles. The proposed invention can develop spatial reasoning skills of players and can be used for education or entertainment.

DETAILED DESCRIPTION OF THE INVENTION

This invention is designed to create 3-dimensional geometric shapes or figures using building blocks with mounted tile faces and friction edges in a manner described below.

Multi-faced Building Blocks (MBB): The multi-faced building blocks are designed as multiple interconnected unit cubes that are fused together (FIG. 1A, FIG. 2, FIG. 3). Fusing of the unit blocks in the design of the multi-faced building blocks is important because it allows for stability during the construction process and helps avoid breakage of the multi-faced blocks handled by a player of any age. The unit cubes that create a building block have at least one common square face. Different configurations of the blocks made of at least three cubic units are possible. The multi-faced building blocks can be made of plastic, wood, metal, clay, glass, or any moldable material; and can be one or a combination of different colors. Instead of fusing the blocks, a single block of an aforementioned shape can also be created using a mold (not shown here). The building blocks can be solid or hollow. Alternatively, the building blocks can be designed as skeletons, with a set of internal support beams that connect all of the mountable mechanisms, which are then covered by a friction edge's material in the shape of an individual block (FIG. 4).

Friction Edges (FEs): The friction edges are designed to increase the friction of each building block during the construction process and to increase the stability of the completed puzzle or geometric structure. The friction edges can be made using rubber, plastic, silicone, or any other material with higher elasticity and friction than the material of the building blocks. The friction edges are connected to a thin layer (made from the same material) covering the surface of the multi-faced building block and are extend outwards on the edges of the block. The cross section of the friction edge without a tile (FIG. 5A) and with a tile (FIG. 5B) are shown in FIG. 5. The design and size of the friction edges allow for a gap between tiles and edges to ease the removal of the mountable tiles (FIG. 5B).

Mounting Mechanisms: Mounting mechanisms are used to connect mountable tiles to each face of a multi-faced building block. The mounting mechanisms on the surface of the block (FIG. 6) and at the bottom of the tile (FIG. 7) are complementary to each other and allow connecting the pieces by geometric, magnetic, or frictional locking. The mechanisms could be of different size and could be round, square, x-shaped, rectangular, or any other shape. There could be one or more mounting mechanisms connecting a tile to a face of the multi-faced building block. A variety of mounting mechanisms has been used in prior arts for tiling a unit cube (U.S. Pat. Nos. 6,679,780B1; 4,003,144; 5,306,198; 8,408,549B2) or for connecting multiple unit cubes together (U.S. Pat. No. 6,237,914B1; 6,679,780B1; 4,003,144; 5,306,198). In our invention, we are incorporating mounting mechanisms to code the solutions of the puzzle using the tiles, and to increase the number of potential solutions of the puzzle. We avoid using unit-blocks as well as mounting mechanisms to connect unit-blocks in the design of each multi-faced building block because this can make the pieces breakable during the construction process.

Mountable Coding Tiles (MCTs): A set of multi-faced building blocks comes with a set of removable/mountable tiles attached to them to create the design of the puzzle. These mountable coding tiles (MCTs) provide hints to the player on how to solve a puzzle (FIG. 8A), without using any reference materials or on-line resources. MCTs also allow a child or player to create and code their own geometric structure with a unique solution for peers to solve. Each set of mountable tiles when attached to the building blocks allows for a unique set of many different solutions (below we describe an example of 20 solutions on a set of 7 multi-faced building blocks) to be solved by players without changing the location of the tiles. A player can solve all the solutions with a given set of tiles mounted in the prescribed locations on each block. Then the tiles can be replaced with a new set of mountable tiles to implement a new design with a new set of solutions for a 3-D geometric structure.

Each face of the multi-faced building block can be covered either by one MCT (FIG. 1B), or by a number of MCTs (FIG. 1A) using mounting mechanisms. The mountable coding tiles can also have a build-in electronic device(s) that allow(s) changing the color or design of each tile. The purpose of the MCTs is to provide affordances/hints to guide the construction process.

The mountable coding tiles can be made of plastic, wood, metal, clay, glass, or any moldable material. Moreover, they can be one or a combination of different colors, designs, ornamentations, or graphic prints. In prior arts, mountable tiles were used to code dice (CH450254; U.S. Pat. No. 8,408,549B2; DE202005001584U1; DE202005006329U1) or to provide a design on the surface of the puzzle. In contrast, our invention uses the mountable tiles to provide hints for solving the puzzle and to define many different solutions within one set of multi-faced building blocks with corresponding tiles.

Puzzle Solutions: In our invention, a set of multi-faced building blocks can be used to build 3-D geometric structures (FIG. 8A). Each block in the aforementioned set can be coded with MCTs to provide hints and help the player guide the solution (FIG. 8A, FIG. 8B). The solution is a distinct pattern or design that can be easily recognized when the structure is completed (FIG. 8A, FIG. 8B, FIG. 17). The puzzle solutions can be coded on a set of multi-faced building blocks to create any N by N by N cube (with N greater than 2), or 3-D geometric shapes other than cubes.

With respect to geometric structure in a shape of a cube, in prior arts, the solutions have been coded with a unique color or design on one or multiple faces of the completed puzzle (U.S. Pat. No. 5,306,198; US2016/0096106A1; U.S. Pat. Nos. 6,422,560B; 6,237,914B1; 5,785,319). In all of those cases, the number of solutions coded are limited and are permanent.

Our invention is different because it intentionally codes each face of the multi-faced building block, which allows a player to build additional solutions using the same set of blocks. The solutions change based on the orientation of the multi-faced building blocks in the final geometric structure. In addition, our multi-faced building blocks with removable tiles allow the players to change the design with a new set of removable tiles generating a new set of solutions.

In the case of a set of seven building blocks as presented in FIG. 9, we coded 20 unique solutions (FIGS. 10-17). To show coding of each of the 7 multi-faced building blocks (FIG. 9) we present all 6 possible views (front, top, right, back, left, and bottom) of each block coded with MCTs using letters (FIGS. 10-17). Each letter represents one of the possible 20 cube solutions (FIG. 17); for example, in FIG. 17 the solution is represented by the letter F coded on the top of the completed puzzle (FIG. 17). MCTs that code solutions are used on portions (90 unit-squares) of the multi-faced building blocks that can be visible on a face of any completed 3by 3by 3 cube. The faces of the seven multi-faced building blocks that never appear as part of the surface of any completed 3by 3 by 3 cube (FIG. 17) are left blank (FIGS. 10-17). For such faces, we use tiles of neutral color (these will not code a cube solution).
